\Forvthe purpose of-ill lstratingzthe invention, I have shown inethe accompanying drawing atypical embodiment of it, which, in practice, will givelreliable and --satisfaotory results. It is, however, to be understood that this embodiment is typical only and that the various instrumentalities of which my invention consists can-be variouslyarranged and organized, and that the inven, tion is not limited to the preciseiarrangement and organization of these instru nentalities as herein s et forth.

- This "holder; is made of a single sheet. of

material and preferably of spring; metal, the a marginal portions of which are outwardly deflected to --1":orm,the. resilient flanges :2aand 3 respectively. Each! flange has its edge inwardly deflected, as at 4, to form; a; guide or shoulder. c

fThe .free ends ofthe holder are of; reduced width, asat 5, and arebent overthe cover 6 randpressedeagainst-itand:the free ends terminate in the terminals 7 which pass'throughthe apertures=:8 in theibody portion of the hol der sothatthe "holder is rigidly securedto thecover. Thefianges 2 and 3 I at one end are "laterally :deflected, as at9, toifonrnrastop. 7 l

. lOi designates. the filler which isprovided along its'inner marginal .edge -=with-the spaced apertures 11. @The sheets I of the filler are secured together by securing lineal-11s -12 which consists of a wire having the fr'ee ends hentfin opposite directions asst-13- and 14, Thewire -12 is'bent to provide othei'longitudinally extending portions 15 and :16 which are connected by the portions 117 at right angles thereto. The zwire is passed through one of the-aperturesvll sothat the portions 17 :extend therethrough and 1 the free ends 13 and cl/liare'insert-ed into-the apertures with which (they, respectively, reg ster.

ll'nsteadof employing-a single wire-Imay employ twowires 18"; and.= 1-9' respectively, see Figure 6, the free ends of the wire18heing deflected in 1 one direction as shown at 20 53-1 and the freeends of the wire itiheing two wires are employed, it is preferable to employ apertures 24 in the filler 10, which the free ends of the wire substantially fill.

In the operation, assuming that the holder has been secured to the cover and the single wire is employed to secure the sheets of the filler in assembled position, the filler is inserted between the flanges of theholder so that the wire will lie beneath the shoulders 4. The filler is then slid into position until it engages the stop member formed by the inturned flanges 9. In case the two wires are employed to secure the filler in assembled position, the two wires are assembled as shown with respect to the filler, and the filler is then inserted so that the wires 18 and 19 pass beneath the shoulders 4.

The purpose of having the side flanges 2 and 3 resilient is to enable the holder to accommodate fillers of different widths. As the holder is preferably made of spring metal, the flanges will normally incline towards each other, and when the flller is inserted these resilient flanges will be under tension and firmly grip the filler, so that there is no likelihood of its becoming accidentally disengaged from its holder.

It will be noticed that where a single wire is employed to secure the sheets of the filler in assembled position the hole through which the'portion 17 of the wire passes is elongated and as illustrated, it is of an oval contour. This provides for the use of fillers of different thicknesses. The wire itself is preferably of comparatively soft metal so that it can be bent at the points where the portion 17 connects with the longitudinal stretches of the wire so that the filler will be properly retained in assembled position and the free ends can be brought into registry with apertures in the filler.

In case two wires are employed to retain the sheets of the filler in assembled condition, the holes into which the free ends of such wire passes, are preferably slightly larger than such free ends.

It will thus be apparent that irrespective of the thickness of the'filler, the free ends ofeither a single wire or a number of wires can readily be brought into registry with the apertures into which they are intended to extend and the sheets of the filler will be retained in assembled position when the filler is slid into place between the resilient side flanges of the holder.

If a single wire is employed, one stretch is preferably longer than the other so that the free ends will engage different apertures. If two wires are employed they may be of the same or of different lengths, as is apparent, althoughI preferably use wires of the same lengths.

It will be apparent that my present invention can be very economically manufactured since the holder is formed from a single sheet of material and if one wire is employed to bind the leaves of the filler together, only two parts are necessary.

The holder is secured to the cover by fastening devices which are integral with the holder. I

This invention, although not limited to such use, is specially adapted to be employed in conjunction with fillers, the leaves of which are so thin that they cannot be retained in position by the ordinary type of ring binders where the rings go through apertures in the leaves.

It will now be apparent that I have devised a new and useful loose leaf binder for memorandum books and similar devices which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described, a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modificationin various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A loose leaf binder,'comprising a holder adapted to be secured to a cover and having resilient side flanges, each of which has its free marginal edge bentinwardly to form a shoulder, a filler insertable between said flanges, and fastening means for said filler adapted to lie beneath said shoulders when said filler is inserted between said flanges and provided with free ends deflected to pass into the filler and retained therein by said side flanges.

2. A loose'leaf binder, comprising a holder formed from a single sheet of material and adapted to be secured to a cover, said holder having resilient side flanges the free marginal edges of which are bent inwardly to form shoulders, and a stop at one end, a filler having laterally spaced apertures and insertable between said flanges to engage said stop, and fastening means comprising a wire having free ends to enter diflerent apertures with which they register, said .means co-operating with said shoulder to retain said filler in place in the holder.

3. A loose leaf binder, comprising a holder adapted to be secured to a cover and having resilient side flanges the free marginal edges of which are bent inwardly to form shoulders, a filler having apertures and insertable between said flanges, and a wire passing through one of said apertures and having longitudinally extending stretches, the free ends of which extend in opposite directions into diflerent filler apertures with which they register. 1

4. A loose leaf binder, comprising a holder adapted to be secured to a cover and having resilient side flanges with shoulders, a filler having apertures one of which is elongated and insertable between said flanges, and a wire passing through said elongated apere ture and having longitudinally extending stretches extending laterally in the same direction on opposite sides of the filler, the free ends of which extend into different filler apertures with which they register.

5. A loose leaf binder, comprising a holder adapted to be secured to a cover and having resilient side flanges with shoulders, a filler insertable between said flanges, said filler having apertures near one of its marginal edges and two wires with deflected ends arranged on opposite sides of the filler and disposed laterally thereof with their ends extending into the different apertures with which they register, said wires being adapted to engage said shoulder when said filler is inserted between said flanges.
